Assetion : The green manganate is paramagnetic but the pruple permanganate is diamagnetic in nature.
Reason : `MnO_(4)^(2-)` contains on upaired electron while in `MnO_(4)^(-)` all electrons are paried.

A

Statement-1 is true , Statement-2 is true and Statement-2 is correct explanation for Statement-1

B

Statement-1 is true, Statement-2 is True and Statement-2 is Not correct explanation for statement-1

C

Statement-1 is true, Statement-2 is False

D

Statement-1 is False, Statement-2 is True

Text Solution

Verified by Experts

The correct Answer is:
A
Statement-1: Correct statement and statement-2 is correct explanation of statement-1
Green `tooverset(+6)MnO_(4)^(2-)-[Ar]^(18)3d^(1)4S^(0),` there is one unpaired electrons, so paramagnetic.
purple to` overset(+6)MnO_(4)^(2-)-[Ar]^(18)3d^(0)4S^(0),` here all electrons are paired , so diamagnetic.
